D)Na⁺

Question

Quizplus · Accepted Answer

The rest membrane potential in animal cells depends largely on nongated K+ channels. This is because the concentration of K+ ions is typically higher inside the cell than outside, and the membrane is more permeable to K+ ions than to other ions such as Na+. As a result, K+ ions diffuse out of the cell more readily than Na+ ions diffuse into the cell, causing an overall negative charge inside the cell relative to the outside.
